Advice needed please, I have recently converted an aristo b unit to dcc via a massoth XL decoder, the same massoth decoder is fitted to the a unit, both run fine on dcc, when placed on an analogue track the b unit runs in the opposite direction, even when turned around, both decoders are set up the same, ie speed steps etc, there is also a track pick up cable bridging the two units and nothing shorts on dcc or analogue, any ideas welcome

There will be a CV that sets the direction of the motor,

But I don't have the information to hand....
